PRESS BUTTON.

Application filed May a,

To all'whom it may concern: I,

' Be it known that I, HANs FRYM, a subject of Germany, and residing at Stolberg, Rhine State, Germany, haveinvented. a certain new and useful Press Button, of which the following is a specification.

It has already been proposed, in connection with press buttons, to arrange the sewing holes in a sunken position relatively to the surface of the disc of the press button parts in order to obviate a piling up of the sewing threads on the face of the disc of I the button after repeatec'l stitching. In the prior devices the sewing holes are formed by stamping out portions of the said disk 1 sewing holes on the discs within the bound I ary of a ring fixed in the bent edge of the disc, the said ring being, in the socket part,

a portion of the spring catch itself. The

sewing threads are, therefore, caused to engage the ring and'bear thereon, so that they are not damaged by sharp edges. The

ordinary button in which the spring catch is placed in position by machinery, may be used with. the present invention.

The accompanying drawing illustrates, by way of example, a construction according to the invention on an enlarged scale.

Figure 1 is a bottom. plan view of the,

socket part. 1 i

40 v Figure 2 is a vertical section on the line 2-2 of Figure 1;

Figure 3 is a vertical section through the head part, e

Figure L is a plan view of the latter.

As illustrated in Figures 1 and 2, the edge 0 of the disc at of the socket part is preferably bent and flanged. The sewing holes are formed partly in the bent portion of the edge 0 and partly in thedisc a, in

other words, and as shown in Figure l,

the edge 0 and a portion of the disc at are cut away to form holes 6, so thatno edge is left at those points and thus the threads do not pass over the disco. The bent and flanged edge 0 receives a ring (Z of round cross section which is preferably a portion of the spring catch member and also forms a support to the sew ng threads 6.

The sewing threads are passed over the I uncovered portions of the ring cl and are not damaged thereby owing to its round cross-section, The' material is preferably firmly pressed against the bent edge 0.

Referring to Figures 3 and 4, the disc a of the button proper is similarly provided with a bent edge 0 wherein a ring d is located. The sewing holes I) are also formed'by cutout portions on the edge 0' and disc a, the method of securing the ring cl in position being identical to that re-,

sorted to for the socket part. It is, of course not necessary that the extreme edge be cut out to form the sewing holes; the said edge may beleft untouchedand bent under the ring as in the present case, and sewing threads will bear directly on the said ring.

Having now particularly. described and explained the nature of my said invention and in what manner the same is to be performed, I declare that what I claim"is- 1. In a press button, a. disk having apertures sunk below its surface and adapted to receive the threads employed in securing the disk in position on a garment or the like, the edge of said disk being bent inwardly, and a ringsecured in the bent edge of said disk and forming the outer boundary of said apertures, the portions of the bent edge ad acent the outerperiphery of said ring being cut away in order to permit the sewing threads to bear directly on said ring. v

2. A press button as claimed in claim 1 in which a spring catch is integral with said ring. i

3. A press button including a disk having apertures sunk below its surface, a ring formingthe outer boundary of said apertion.

connected to the edge of said disk and in Which said ring is of circular cross sec- 1O tures, the edge portion of said disk being In testimony whereof, I hereunto afiix my cut away adjacent said apertures to permit signature in the presence of two witnesses. the threads used in connecting the disk to HANS PRYM. a garment or the like to bear directly on Witnesses: said ring.
